Complaint Review: Premier Resort Marketing

This company called and said they could sell our timeshare (which they had all the details on) at a higher price than what was paid initially. Then came up with Mexico had put a Federal tax on the sale. Then another email to say that there was also a state tax. Then another email to pay for the escrow tax and we would have the money in 3 business days. After not receiving the money, 3 phone calls were made with no response and no return calls. That has been almost a month now. Don't know where to go from here. We did find out after the fact that this scam has been done before  with just a company name change.
